National Advisory Council on Unpaid School Meal Debt Act This bill establishes the National Advisory Council on Unpaid School Meal Debt in Child Nutrition Programs. The council must provide recommendations to the Food and Nutrition Service (FNS) with respect to addressing unpaid school meal fees by ensuring that students are not stigmatized and school food authorities can maintain fiscal solvency in order to ensure the long-term viability of school meal programs. The FNS must use the recommendations to issue guidance with respect to addressing unpaid school meal fees.
